: There are only nine Avatara at a time. The "other
: Avatara" which you refer to are best classified
: as 'wizards' or 'archmages' or 'mages' or 'sorcerers'
: since they cannot be called Avatara.
What I believe is that Avatara is a certain type of mage, one who can fight and wield powerful Dreams, such as Dispersal Dreams, just as Warlock is a type of mage who sell their souls for the power of flame.
So there could ahve been other Avatara, but the Nine were the chief among them, a ruling council for the Province, if you will (which you must ;) ).
